One of the important features of my invention consists in embossing the pocket por.-y

`tion of the mount to form projecting ridges the corner of the card is inserted in the A pocket the ridges grip and hold it thereby retaining the mount in yrm position on thecard. This feature is ofy great advantage because it permits the mounts to be positionedon the supporting surface with exactness since the mounts when placed on the corners of the object to be mounted will grip the same and retain their position'even when the object is freely handled.

Referring tothe drawings, l0 in'dicas ing straight sides 12 and a corner receiving pocket 14 which is right-angled for receiving and fittingl the squared corner of a card or similar object. The side edges of the pocket lieat angles of forty-five degrees to the sides 12. The ocket may, if desired, be triangular in plan, ut it is preferably rightangled in order to avoid covering any portion of the picture in the card and to increase, its attractiveness in appearance when mounted. The pocket 14 is formed integral with the body portion 10 by turning over two contiguous edges of the latter into a right-angled relation with each other and then applying thereto a right-angled cap which is preferabl made of two or threeI pies to impart sti ness and durability thereto, and to permit the mounted card to be removed there- -'frmly gripped to hold This construction isillustrated in F1gures paratively thin paper the pocket unless stif-` fened by a cap of comparatively heavy material is very easily torn and injured in the mounting operation or afterward in handlingr theA album-- or other 'supporting surface. I-Ieretofore, this`has;been one objection 'to a corner mount formed of one folded'piece. Furthermore, the cap must be substantially coextensive with the flanges of the pocket for if the latter extend but a part way from the fold to the edge of the pocket,I the latter is thereby weakened and it is open to the additional objection that the edge of the card or print may encounter the edges of the flanges and either prevent the full entrance of the card and injure the mount or buclle the card or print.

The .form of the bottom edge 16 of the body portion of the mount is more or less immaterial so long as the body portion is of suffi-A line 16 which will leave the end of the strip properly 'shaped for the forming of the next mount. .The back face of the corner mount is coated with any suitable adhesive.

The pocket portion of the mount is embossed in any suitable manner, the embossed lines being preferably arranged to form a design to enhance its appearance. In the form shown in the drawings the embossing comprises an inset continuous line 18 parallel to the edge of the cap or the pocket. The main purpose of the embossing, however, is to secure an interlockin relation between the innerface'of the poc et portion 14 and the body ortion 10 so that the corner of a card or print inserted into the pocket will be the mount thereon.

6 and 7 of the drawings in which 18 indicates the embossed or depressed line in the pocket portion 14, and 20 the correspond ing' embossed or depressed line in the body portion 10. TheL inner or lower face of the pocket portion is in engagement with the upper face of the body portion thereunder so that the inner ridge formed `on the pocket bythe embossing projects into and engages the depression in the body portion formed in the same way. When the corner of the card or print is insertedfinto the pocket, 1t separates' the two engaging faces but the tendency of those two parts to .return 'to a normal engaging position operates to grip lthe inserted corner.

In carrying out the method of making my corner mounts, I first prepare a continuous strip 30 of paper or other material suitable for the body portion of the corner, of the exact width of the mounts. Preferably I use a thin tough paper not easily torn and coated .with a lsuitable adhesive 32 on one side.

-right-angled pocket butnot inclosed condition.

Next, I prepare a right-angled cap which may be died or stamped out of a second'- continuous strip 42 of paper or other suitable material which is uncoated, the cap being of a size to cover said flanges 38 to complete the pocket. The strip 42 is preferably, when paper is used, comparatively thick, heavy and tough or may be made of double or treble layers or plies and is uncoated.- In applying the cap to the fianges 38 to complete the pocket, the cap or the strip 42 from which the cap is cut is moistened and when the moistened cap is pressed down upon the ianges 38 immediate adhesion results. I'have found in this connection that the moisture must be applied to the cap and not to the adhesive coated flanges for if the application is made to the latter it will be practically impossible to placel the cap in proper position on the flanges and to secure a proper adhesion between the two except by great 'care and a long continued pressure. When the cap alone is wet permanent and complete adhesion may be secured by a quick blow or pressure exerted for but an instant.

The application of the capmay be accomplished by any suitable die or stamp and the embossing of the pocket portion of themount should preferably be done in the same operation because it 1s much more effective and permanent when performed on a. wet or moist cap. The cap being of comparatively heavy material takes the impression of the embossing better when` wet and holds it better because it dries in that form. 'I he embossing therefore tends to stiffen the cap.

In Figures 6 and 7 the edge of the cap is shown as just a trifie larger than the flanges. I have found that if the cap overlaps all sides the exposed surfaces and edges of the flanges, one sixty-fourth of an inch approximately, and the surface of the embossing die is formed Ito press the pocket portion of the 'corner into the shape in cross-section shown in said figures, that the edge ofthe cap on all sides is bent down over and conceals the edges of the ianges. This is important especially when a cap having a dullffinish is used because the adhesive coated side of the mount has a high gloss and unless the cap laps down over the lines of fold ofthe flanges, a thin line of gloss hand with is visible on those edges and ruins the appearance of the mount. mounts of this form are made with caps having dull or unfinished surfaces for use in mounting prints or photographs the importance of avoiding a visible line of gloss in the completed mount is apparent for no mattei' how thin the line may be, it becomes especially noticeable in the mounting of a photograph. At the time the mount is completed by the application of the cap, it may be severed from the continuous strip along the line 16 which leaves the end of the strip in the exact form shown in Fig. 1 ready for the making of the next corner mount.

Althouwh my method may be performed by the use of a. few simple utensils, yetI have found that certain steps of my method can be carried out with vmost advantageous results by the machine shown and described in an application for United States Letters Patent filed by me June 17, 1924, Serial No. 720,540. In the use of mounts constructed in accordance with my invention, four mounts are placed on the four corners of the object to be mounted with the corners fully inserted in the mounts, the adhesive coated backs of the mounts moistened with a 'small sponge or, better still the surface on which the card is to be mounted is moistened at the points where the mounts are to be aiiixed and the card is then laid on the supporting surface and the mounts pressed down. If the supporting surface is moistened rather than the adhesive coated backs of the mounts a perfect bond between the two is secured with very little pressure and that exerted only for an instant. Furthermore, the caid cannot slip `to one side or the other when the backs of the corners are wet and pressure is applied.

The fact that the completed mounts are not fiat so far as the pocket portion is concerned but are in the shape shown in Figure 6 is of importance because it facilitates in such a large measure `the mounting of cards or photographs in an album or on a similar supporting surface. This shape is given the mount by the embossing die at the time the corner cap is applied while the cap is moist and consequently the mount dries in that shape Whichis thereby made permanent. At the same time, the pressure of the die tends to press all the layers of the pocket portion of the mount into close contact as shown in Figure 6. When the corner of a card or photograph is inserted inthe pocket portion of a mount, the body portion 10 of that part ofi the mount is separated from the pocket but!l the tendency of the mount ,to return to its v voriginal position results in the corner of the Since practically all.

the mounts on its corners and I have found that this gripping action is so strong that the mounts are not disturbed. even when the card is shaken violently in an attempt to displace the mounts. The amount of labor and time required for mounting cards or photographs in an album, for instance, with the use of mounts made in accordance with my invention is greatly reduced; so much reduced and the operation is rendered so simple and may be performed with such rapidity that it becomes a pleasure rather than an arduous task.

It is to'be understood that my invention is not to be'limited to the exact form of construction and the exact method herein shown and described since both may be varied to certain extents Within the purview of the following claims.

What I claim is 1.
